Save Money to Invest

What is a savings account and how much does it pay?

A savings account is the simplest way to save in New Zealand: you put money in, the bank pays interest, and you can take the money out when you want. The rate is variable, which means the bank can change it at any time — it usually tracks the Reserve Bank's Official Cash Rate with some delay. The main value of a savings account is safety and access, not return: this is where your emergency fund and money you might need at short notice should sit. In this guide we cover how the interest is worked out, how it is taxed, what the Depositor Compensation Scheme covers, and when it is time to move the money somewhere else.

How interest on a savings account works

The rate is always quoted per year, but it accrues on your balance day by day and is usually paid monthly. If you have $20,000 in an account paying 3% a year you earn roughly $600 in interest over a year, before tax, assuming the rate and balance stay the same. Because the rate is variable it can go up or down during the year — so always compare the current rate, not an old figure in an ad.

Some accounts pay a bonus rate only if you meet conditions each month — a minimum deposit, no withdrawals, or a set number of card transactions. If you miss a condition you drop to the low base rate. Read the terms before you move money, and check whether the headline rate applies to your whole balance or only up to a cap.

RWT and the Depositor Compensation Scheme

Interest on a savings account is taxable income. The bank deducts Resident Withholding Tax (RWT) at the rate you have told them, which should match your income tax rate (10.5%, 17.5%, 30%, 33% or 39%). If your RWT rate is set too low you can end up with a tax bill; if it is too high you have overpaid. Give the bank your IRD number and the correct rate.

Since 1 July 2025 the Depositor Compensation Scheme protects your deposits up to $100,000 per depositor, per institution, if your bank or non-bank deposit taker fails. Cover is automatic — you do not need to opt in. It is run by the Reserve Bank of New Zealand.

When a savings account is enough — and when it isn't

A savings account is the right place for your emergency fund, for money for a trip next year, and for a house deposit you will use soon. The point is that the amount is safe and reachable, not that it grows as much as possible.

For money you will not touch for five years or more, inflation eats a large part of a savings account's value — that is where broad, low-cost managed funds or ETFs are a common alternative, with the risk that involves. A common approach is to keep the emergency fund in a savings account and long-term savings in funds, often through KiwiSaver or a separate investment account.

Frequently Asked Questions

How much interest does a savings account pay in New Zealand right now?
It changes with the Reserve Bank's Official Cash Rate and differs between banks. Bonus-saver and notice-saver accounts usually pay more than an on-call account, if you meet the conditions. Always compare the current rate after RWT before you choose.
Is the money in my savings account protected?
Since 1 July 2025, yes — up to $100,000 per depositor, per institution, under the Depositor Compensation Scheme, if the bank or licensed deposit taker fails. If you have more than that you can spread the money across several institutions to stay under the limit at each.
Savings account or term deposit — which is better?
It depends on when you need the money. A savings account is flexible; a term deposit usually pays a higher, fixed rate but locks your money away for the term (with a penalty to break it early). Many people use both: an on-call buffer, plus term deposits laddered over different maturities.
